Pinguicula esseriana

The Mexican butterwort is a plant native to the humid areas of Mexico. It thrives in environments with consistent moisture, although it can tolerate short dry periods. For optimal growth as an indoor plant, water it twice a week and maintain high humidity. You can achieve this by regularly misting the plant or using a pebble tray to create a tropical rainforest-like atmosphere.

Mexican butterwort is native to habitats that receive ample sunlight, such as open bogs and sunny wetlands. It favors full sun, although it can also tolerate partial sun.

Mexican butterwort favors moderate temperatures, about the same as what people typically find comfortable. It does best in conditions that are neither too hot nor too cold. The main concern with high temperatures is the chance of sunburn, so providing some shade in summer is recommended to prevent excessive heat. When temperatures fall, Mexican butterwort goes into dormancy. If you want it to keep growing continuously, you need to keep temperatures higher over winter. Frost can damage the plant and should be avoided.

When repotting Mexican butterwort, pick a pot 1-2 inches (2.5–5.1 cm) larger that has good drainage. Use a well-draining potting mix. Repot in spring or fall, making sure the root ball sits slightly lower than the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.

The Mexican butterwort has sticky leaves and requires minimal pruning, which is best done from early to late spring. Removing dead leaves promotes growth and helps prevent disease. Regularly cleaning away debris ensures the plant remains functional and looks good. Pruning not only maintains the health of the plant but also enhances its vigor and improves its ability to catch insects.
